Application led ctober 1915. Serial No. 54,802.

To all whom t may concern.'

Be it lmown that T, FELIX J. MCGUANE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Liquid-Elevator, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed. for raising water out of a well by air pressure and cross reference is hereby made to my copending application for Letters Patent on a liquid elevator; Serial No. 710,599, tiled July 20, 1912, that application showing an elevator embodying many of the principles shown in this application No. 54,802, the claims in the said application No. 710,599 being drawn broadly to cover the construction shown in both of the said applications, and the claims in this application No. 54,802 being drawn to cover features peculiar thereto.

@ne object of the invention is to improve theshiftable valve structure which; being located in the well, opens and closes to admit water to the action of the air pressure.

A further object of the invention is to provide novel means for controlling the ad.- mission of air to the mechanism Vwhereby the valves in the well are shifted.

A further object of the invention is to provide a novel means whereby the actuating mechanism will be under air pressure only when the structure is in operation.

It is within the province of the invention to improve generally and to enhance the utility Vof devices of that type herein disclosed.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In Fig. 1 of the drawings, the complete device is shown, and it will be understood that Fig. 1 is largely diagrammatic, the view being illustrative merely of one of the many arrangements possible between the various component mechanisms to be described in detail hereinafter..

Regarding Fig. 1 as presenting a typical but not obligatory showing, there appears a chamber 1 defined by a side wall 2, a lower platform 3 and an upper platform 4. The well casing is shown at 50 and extends upwardly to the lower platform 3.

An engine or motor indicated at 5 may be mounted upon the upper platform 4 or elsewhere, the engine 5 being operatively connected in any desired manner with an air compressor 6 of any approved type. An air tank 7 is shown in the present instance as mounted in the chamber 1 and a pipe 8 leads from the compressor 6 to the air tank. In the pipe 8 is interposed a check valve 9 valve 12 being indicated by the reference e character 14. Note Fig. 11. Secured to the stem 14 of the valve 12 is a pinion 15 meshing into a rack 16 formed upon a plunger 17 carrying a weight 18, the plunger being guidedin a boss 138 on the top of a tubular casing 19. Located within the casing 19 Y isan eXpansible'element shown in the form of a bellows 2O with the upper portion of which the lower end of the plunger 17 is connected. 1n order to support the plunger 17 for right line sliding movement, the casing 19 may be provided with an arm 139 having fingers 140 which span the plunger, there being a roller 141 j ournaledy upon the arm 139 between the fingers 140, the roller 141 receiving one edge of the plunger 17.

The invention includes a tank 22 in the top of which air may be trapped, the lower portion of the tank 22 containing` water. A pipe 21 connects the tank v22 with the bellows 20. Entering the tank 22 is a pipe 23 of any desired length, the pipe 23 carrying a faucet or cock 24. 1t is through the pipe 23 and the faucet 24 that the water from the well 50 ultimately is delivered.

YBranched offV from the pipe 21 and communicating with the pipe 23 is a pipe 500 in Vwhich is interposed a check valve 501 closing toward the bellows-casing 19. nterposed in ther pipe 21 and located between the tank 22 and the pipe 500 is a needle valve 502.

LocatedV in the pipe 23 upon the opposite side of the tank 22 from the needle valve 502i-s a check valve 503 which opens toward the tank 22.

Communicating with the pipe 23 is a pipe 25 in which is interposed a check valve 26. The check valve 26 opens toward the tank 22 and closes in an opposite direction. pipeV 25 constitutes a part of the water delivery system and communicates with a casing denoted generally by the numeral 27 and located in the well tubing 50. The casing 27 is shown in detail in Fig. 4.

The casing 27 as shown in Fig. 4 is a composite structure and includes a base 28 provided with an opening 29 surrounded by a gasket30 against which abuts a-coupling 31, the coupling being held inplace by a screw 32 threaded into a bracket 33 forming a part of the base 28. r1`he lowerend of the pipe 25 is connected with the coupling 31. Assembled with the base 28 is a vtube `34 in which is mounted a thimble 35 having a lateral projection 36 through which leads downwardly a duct 37 for a purpose to be pointed out hereinafter. Located within the thimble 35 is a bushing 38 having a flange 39 which overhangs the upper end of The the thimble 35. Mounted on top of the flange 39 is an abutment ring 40 which may be resilient. Superposed upon the abutment ring 40 is a retaining ring 41, and securing elements 42 pass downwardly through the retaining ring 41, through the abutment 40, through the liange 39 and enter the upper end of the thimble 35. Surrounding the thimble 35 is a tube 43 into which is inserted a strainer head 44 having perforations 45. Surrounding the exterior of the strainer head 44 is a line meshed screen 46. Mounted in the strainer head 44 is a bushing 47 having a flange 48 which bears upon the lower end of the strainer head. A resilient abutment ring 49 lies against the flange 48, a retaining ring 51 coperates with the abutment ring, and securing elements 52 unite the parts above mentioned with the strainer head 44.

Mounted to reciprocate in the upper end of the bushing 38 is a lower valve 53 of tubular form, the same'being provided in its side wall with ports 54 which taper toward their upper ends. At the upper end of the lower valve 53 there is formed a iange 55 which coperates with the abutment ring 40 to limit the downward movement of the valve. The space below the valve 53 constitutes a lower chamber 56 and the space above the 9 said valve constitutes an upper chamber 137. Mounted to reciprocate in the bushing 47 is a tubular upper valve 57 having in its side wall, ports 58 which taper toward their lower ends. The upper valve 57 includes a iange 59 which coperates with the abutment ring 49 to limit the upward movement of the valve. The stem of the lower valve 53 is shown at 60 and is united by means of a ball joint 61 with a connecting rod 62, the upper end of which is united by means of a ball joint 63 with the stem 64 of the upper valve 57, the upper end of the stem 64 being united by a ball joint 65 with a main operating rod 66 which will be alluded to repeatedly hereinafter.

A tube 67 is threaded into or otherwise secured to the upper end of the strainer head 44, the tube 67 passing upwardly through the lower platform 3. Surrounding the tube 67 and vertically adjustable thereon is a base plate 68 held in place by a set screw 69. The base plate 68 copcrates with the lower platform 3 to support the tube 67 and the casing 27 in vertically adjusted positions within the well tubing 50.

The upper end of the tube 67 carries a supporting frame 70 upholding a main cylinder 71 in which reciprocates a main piston 72 secured to the upper end of the main operating rod 66. As clearly shown in Fig. 2, a fulcrum post 74 is pivoted at 73 to the base plate 68, the upper end of the fulcrum post 74 being pivoted as shown at 75 to the intermediate portion of a lever 76 upon one end of which a weight 7 7 is adjustable longitudinally of the lever, the weight being held in place by means o1 a set screw 78. The other end of the lever 7 6 terminates in spaced fingers 79 which, as shown best in Figs. 8 and 9 span the tube 67. The fingers 79 of the lever 76 engage beneath a cross arm 80 inserted through the main operating rod 66 and held therein by set screws 81, the tube 67 being provided with longitudinal slots 82 in which the cross arm 80 is adapted to reciprocate.

By means ot retaining bands 84, a tubular valve casing 83 is attached to the main cylinder 71, the valve casing 83 preferably being open at its ends, wholly or in part as shown in Fig. 10. From the lower end of the valve casing 83 a port pipe 85 leads to the upper portion of the main cylinder 71, and from the top of the valve casing 83, a port pipe 86 leads to the lower portion oit the cylinder 71. A stem 87 is mounted to move within the casing 83, the stem carrying an upper valve 88 and lower valve 89.

By means of a pivot element 90, the upper end of the valve stem 87 is united with a link 91 having a longitudinal slot 92 in which is mounted to reciprocate a pin 93 which, as shown in Fig. 3, is carried in one end of a walking beam 94 fulcrumed intermediate its ends at 95 upon a standard 96 fixed to and rising from the upper end of the main cylinder 71. Intermediate its ends, the walking beam 94 is provided with an upstanding finger 97 supporting a cross rod 98 to which are attached the upper ends of retractile springs 99, the lower ends of which are connected as shown at 100 to the upper end of the main cylinder 71. rlhat end of the walking beam 94 which is remote from the pin 93 carries a pin 101 mounted to move in a slot 102 formed longitudinally in a link 103 pivoted at 104 to the upper end of a combined valve-actuating and dash-pot rod 105 mounted to reciprocate in a guide 106 attached to the main cylinder 71. A dash-pot cylinder 107 is mounted on an arm 108 surrounding the tube 67 and vertically adjustable thereon, the arm 108 being held in place by a set screw 109. Attached to the lower end of the rod 105 is a head 110 adapted to reciprocate in the dash-pot cylinder 107. The lower end of the dash-pot cylinder 107 carries a coupling 111 with which is connected the lower end of a by-pass pipe 112, the upper end of which communicates with the dashpot cylinder 107 near to the top thereof. The by-pass pipe 112 comprises a filling cup 114 whereby oil or another liquid may be introduced into the dash-pot cylinder 107. rlhreaded into the coupling 111 is a needle valve 115 cooperating with the lower end of a passage 116 in the coupling 111.

As shown best in Fig. 8, a tube 117 surrounds the dash-pot rod 105, the tube 117, if

desired, being formed in two parts, the adjacent ends ot which are threaded into an abutment 118, the abutment 118 thus being lined upon the tube 117. The abutment 118 is oit proper size to pass freely through an opening 119 formed in an extension 120 united by mea-ns of securing elements 121 with the cross arm 80, the extension constituting to all intents and purposes, a part of the cross arm. Threaded or otherwise secured on the upper end or' the tube 117 is an upper head 122 which, through the medium a cotter pin or the like, may be connected with the dash-pot rod 105. lnterposed between the abutment 118 and the head 122, and movable longitudinally or the tube 117 is an abutment which at times coacts with the lined abutment 118 and is supported thereby, a compression spring 125 being interposed between the head 122 and the movable abutment 124. An abutment 126 is movable upon the tube 117, longitudinally thereof, the abutment 126 being located below the extension 120 orf the cross arm 80. flt times, the movable abutment 126 co operates with the iXed abutment 118, a compression spring 127 being mounted between the abutment 126 and a iixed abutment 128 attached by threading or otherwise to the tube 117, a cotter pin or other suitable connection being employed for uniting the abutment 128 with the dashpot rod 105.l As hereinbefore stated, the abutment 118 is of suliciently small diameter to pass through thn opening 119 in the extension 120 of the cross arm. 80. The abutments 124 and 126, however, are suiliciently large in diameter so that they cannot pass through the opening* r1`he lower end of a main air pipe 130 enters the projection 36 of the casing 27 and communicates with the duct 37, a cleaneout plug 131 being mounted in the end of the projection 36. The main air pipe 130 com-l municates with a branch pipe 132 leading to the valve 12. 1n the branch pipe 132 is placed a hand valve 133, and hand valves 134 and 135 are placed in the main air pipe 130 upon opposite sides of the branch pipe 132. The upper end 136 ci the pipe 130 enters the valve casing 83 intermediate its ends as shown most clearly in Figs. 3 and 10.

will now be pointed out how the water enters the casing 27 of Fig. 4 and is ejected therefrom.

lllhen the main operating rod 66 moves downwardly, the upper valve 57 is unseated and the ports 58 therein are opened. lllater thereupon passes downwardly through the strainer head 4.4 and through the ports 58 into the chamber 137 the lower end of which is closed because the lower valve 53 is seated. During the downward movement of the upper valve 57, air which may have accumulated in the chamber 137 passes upwardly Venters the casing 27 by way of the pipe130 and the duct 37 and it will now be obvious that if the upper valve 57 is seated as shown in Fig. 4l, air accumulating in the chamber 137 willV force the water out of the pipe 25. If, however. the lower valve 53 is seated, air

- accumulating in the lower chamber 56 will force the water out through the pipe 25.

lThe manner ofv charging the air tank 7 is as follows:* Y

The valve 133 may be closed if necessary, the valve 10 being opened. rThe motor or engine 5 is put into operation, driving the air compressor 6, air being forced through the pipev 8 into the tank 7, the function of the check valve 9 with respect to the compressor 6 being obvious. The check valve 26closes toward theV well, and consequently air pressure will be accumulated within the tankY 7. When a sufficient pressure in the tank 7 has been attained, the engine 5 is stopped and the valve 10 is closed' tightly. If the valve 133 has been closed during the operation above described, the same is now opened.

The weight 18 on the end of the plunger l 17 tends toV depress the plunger, the rack 16 iof the pipe 21 into the bellows 20, the latter thereof rotating the stein 14- of the valve 12 through the medium of the pinionV 15, theV weight 18 acting to maintain the valve open whilethewater is being drawn off through Y the ypipe 23 and the faucet 24 as will be eX- plained hereinafter.

' From the tank 7 air under pressure passes by way of the pipe 11, the pipe 132 and the pipe 130 into the casing 27 through the duct 37 as hereinbefore explained.

From the casing 27 water passes by way of the pipe 25 to the tank 22. lf the faucet '24; is closed, that is, duringthe time that no water is being drawn off, the pressure in the tank 22 rises, a quantity of air normally being trapped in the top ofthe tank. rlhe pressure thus created is transmitted by way actuatingthe plunger 17 which, through the medium of the rack 16 and the pinion 15, closes the valve 12. p

' It will -now be obvious that when the faucet 24e is open, the valve 12 will be opened, thus admitting air under pressure into the casing 2,7 through the pipes 132 and 130, and by way of the pipe 136 into other v elements of the structure, the operations of which will be described hereinafter.

vWhen, however, the faucet 24 is closed, the valve 12 will be closed and the air supply will be cut olf. There lore, when the strueture is not in use there will be no waste of air pressure caused by loose or leaky joints. 1f, however, a leakage should take place duo to imperfect joints, when the structure is in operation, this leakage will be of minor consequence, since the structure is in operation, ordinarily but for a short period, compared with the length of time during which it is not in operation.

A. portion of the structure is adapted to secure a positive opening and a tight closing of the valve 12, and to insure that the valve 12 will respond instantly when the faucet 21 is opened. ln order that the bellows 20 may relax instantly, the bellows must be drained promptly when the faucet is opened, and the pressure in the tank 22 must be prevented from retarding the collapse of the bellows. In this connection it is to be observed that when the faucet 211 is opened, the water in the bellows 20 flows into the pipe 23 b v way of the pipes 21 and 500, but cannot iow in an opposite direction, owing to the presence of the check valve 501 in the pipe 500. Again, the needle valve 502 is so set that the pressure in the tank 22 cannot be communicated rapidly to the bellows 20 while the same is emptying. When the faucet 24 is closed, the needle valve 502 causes the valve 12 to act slowly and the iiow of water through the pipe 21 is retarded, and as a consequence, suliieient pressure is stored in the tank 22 so that when the valve 12 does arrive at a closed position, there will be no doubt about its being held closed. 1f the needle valve 502 did not retard the rush of water to the bellows 24, the valve 12 would cut olf the air pressure prematurely without however having effected a complete and tight closure, and if the air were thus cut olf, there would not be secured in the tank 22 suficient pressure to insure a tight closing of the valve 12. The check valve 503 obviously serves to hold the pressure in the tank 22.

liVhen the faucet 24: is opened and the valve 12 is opened, air is delivered into the valve casing 83 intermediate its ends, through the pipe 132, the upper end of the pipe 130, and the lateral extension 136. lresupposing that the valves 88 and 89 occupy the'positions shown in Figs. 3 and 10 it will be seen that air under pressure delivered into the casing 83 by way of the pipe 136 will be delivered by means of the port pipe 86 under the main piston 72 on the main operating rod 66, the latter moving upwardly and carrying with it the valves 53 and 57 inthe casing 27, as hereinbefore set forth. When the main operation rod 66 moves upwardly, the cross arm 80-120 moves upwardly, the fixed abutment 118 passing through the opening 119 and the abutment 124 being engaged by the element 120. The abutment 124 thus is carried upwardly and the spring 125 is compressed, the latter reacting against the head 122 and moving the dash-pot rod 105 upwardly. When the dask-pot rod 105 moves upwardly, the link 103 is carried upwardly, the pin 101 in the walking beam 94 being at the lower end of the slot 102. By this operation, the right hand end of the Walking beam 94 (referring to F ig. 3) is raised and the left hand end of the walking beam 94 is depressed. After the upper end of the finger 97 on the walking beam 94 has swung to the left past the vertical, the springs 99 act to depress the left hand end of the walking beam. The pin 93 in the left hand end of the walking beam 94 ultimately arrives at the lower end of the slot 92 in the link 91 and depresses the link 91 along with the valve stem 87. The pin 93, however, does not arrive at the lower end of the slot 92 until after the upper end of the arm 97 on the walking beam 94 has swung to the left, past the vertical, and as a consequence, a dead center is avoided, it being impossible for the valve stem to stop in such a position that the valves 88 and 89 cover the ends of the port pipes 86 and 85.

`When valve stem 87 moves downwardly, reference being had particularly to Fig. 107 the lower valve 89 passes below the lower end of the port pipe 85 and air is admitted into top of the cylinder 71 through the pipe 136, the casing 83 and the pipe 85. During this same operation, the upper valve 88 moves below the upper end of the pipe 86 and the exhaust passes out through the open upper end of the casing 83. When the parts are in the positions shown in F ig. 10, the air under pressure is passing beneath the piston 72 by way of the pipe 136, the casing 83 and the pipe 86, the exhaust passing out by way of the pipe 85 and the open lower end of the casing 83.

When the main operating rod 66 moves downwardly, the abutment 118 passes througa the opening 119 in the cross arm 120-80, the element 120 engaging the slidable abutment 126 and the spring 127 being put under compression, the latter reacting on the dash-pot rod 105, and an elevation of the left hand end of thewalking beam 94 resulting, due to the action of the link 103, in a manner which will be clearly understood from what has been stated hereinbefore.

llVhen the main operating rod 66 moves downwardly, the cross arm 80, coacting with the lever 76, elevates the weight 77 and upon the upstroke of the main operating rod 66 an important assisting action is given by the weight 77, the inertia of the main operating rod 66 and attendant parts being offset to a large extent, upon the upstroke. When the til rod 105 is ieciprocated, the head 110 is caused to reciprocate in the dash-pot cylinder 107, the oil or other liquid in the dashpot cylinder traversing to and fro by way of the by-pass 112. lThe movement of the rod 105 therefore is retarded and the lineal speed of the rod 105 may be regulated by cutting off the by-pass 112 to a greater or less extent through the medium of the needle valve 115. The rod 105 and connected parts therefore move slowly, but no such movements takes place in the main operating rod 66. An appreciable interval of time elapses between the movements of the rod 66 and when the rod does move, it operates quickly.

The valves 57 and 53 therefore move quickly,

with an appreciable interval of time between their movement, and it is during this interval that the water enters the casing 27 and fills the chamber 137 as hereinbefore described. The interval during which the valves 53 and 57 remain at rest may be regulated by adjusting the retarding effect of the dash-pot mechanism through the medium of the needle valve 115.

The ball joints. of which the joint 63 may be taken as typical, permit a satisfactory operation of the structure even though the reciprocating elements delineated in F ig. 4 be slightly out of axial alinement.

rlhe check valve 26 prevents the water from running back into the casing 27 through the pipe 25 when the pressure is reduced by the initial opening of the faucet 24.
